Shree matangi investment casting manufactures prototype casting from rubber moulds, machined waxes, and epoxy tooling made from a master. Generally, it can pour almost any alloy into the mould for any complex construction of casting. In case of urgent requirements, it can work on the basis of a sketch, drawing. Cad file, or sample [with prior consent]. Investment casting/precision casting or the lost wax process has been in use since the construction of the first pyramid. The egyptians and chinese used the process in their early history to make jewellery and statues. The investment casting method was largely ignored as an industrial process for the fabrication of parts until the demand for rapidly finished parts during world war ii created the need for near net-shape components that could readily be put into their final form. It is a process capable of producing intricate shapes weighing from a small fraction of a gm up to 20 kg or more. Some examples would be aircraft structural parts, components for the automotive industry, military weaponry, jet engines, machinery components, dental appliances. And jewellery. Investment casting produces near-net- sliape configurations, offering engineers and designers freedom of design in a wide range of alloys. More than 125 ferrous and non-ferrous metals are routinely cast. Splines, bosses, serrations. Lettering, holes, and even some threads can be cast.
